MaP Testing
A voluntary test protocol for toilets that measures the ability to remove solid waste, also referred to as "bulk." Cooperatively developed in 2003 by water utilities and water-efficiency specialists in the United States and Canada, it uses soybean paste (miso) as test media, in an effort to replicate "real world" waste. The test is conducted by successively increasing the amount of test media that is flushed until the toilet is no longer able to reliably or completely remove the media from the bowl. Results are reported as a MaP score, which is related to the number of grams of a test media that a toilet can adequately flush.
